Be sure that the marked line is above the heating element.
Cold bending plastic sheets.
Wear gloves as you do this to avoid burning your hands.
Spectar supposedly looks and handles much like acrylic but with the surprising property that it can be cold formed without breaking or whitening and exhibits a memory effect holding a cold bend until reheated.
Set up plastic or acrylic sheet in a simple bending jig.
When you heat acrylic to 160 degrees celsius it becomes soft and bends easily.
Hot bending polycarbonate sheet.
As could be inferred from its name cold curving is the process of bending the whole polycarbonate sheet to create a dome or an arch.
This takes us to another important fabrication process.
Tensions arise during bending and the sheet may straighten out.
Depending on the thickness of the material most plastics can be bent in a gradual radius without negatively affecting the integrity of the material.
Curved polycarbonate sheet on swimming pool enclosure in the formation of such a shape the significance of the cold forming radius comes into play.
Set the sheet of acrylic across the rests on the strip heater and turn it on.

Cold line bending polycarbonate sheet is basically a prelude to fabrication process.
Turn the sheet of acrylic over on the heating element every 30 60 seconds in order to avoid damaging it.
Plexiglas sheet can be cold formed bent at room temperature in a smooth arc and held to a radius by forcing the material into a curved channel support.
It s advisable to proceed with care.
Cold bending some thermoplastic materials can be cold bent without the need to apply heat.
Cold bending is further possible with more types of polyester.
Some materials can even be cold bent using a press brake the same machine used for bending metal.
To set up your plastic or acrylic sheet to bend simple curves for your miniature and model projects you need to first remove the protective covering from the material you wish to bend.
This video is about bending and thermoforming king plastic polymer sheets.
Use long thin 1 inch or so in width test strips to practice your technique and learn how your particular heat source affects your chosen thickness of plastic.
However cold bending is quicker and more favourable than hot bending.
Well this is the opposite of the cold bending polycarbonate sheet.
They place the acrylic sheet over a long thin filament with the bend line positioned precisely above the wire.
The process of cold bending of plastic sheets is the same as bending metal but since plastic is a vivid material than metal it causes more problems.
Alternatively in case you don t want to cold bend polycarbonate sheet apply heat.
